The Life Of Pablo was the first LP to go number one via streaming only back in April of 2016.
The project was originally a TIDAL exclusive. But when 'Ye expanded it out, he only put it on streaming services like Spotify and Apple Music; it was never available for download (save for a moment on his website) and never had a physical copy.
The RIAA certified TLOP platinum this week, making it the first album ever to hit a million sales via streaming only.
Since 1500 streams is the equivalent to one one album sale, that means TLOP has been streamed at least 1.5 billion times.
